5.2 Dual feed
It is recommended to match the presser foot pressure with the fabric. The thicker the fabric, the lower
the presser foot pressure.
The Dual Feed feeds the fabric from above and from beneath simultaneously. This provides an even and
careful feed forward even for smooth and thin materials. Striped and checkered patterns can be matched
perfectly by even feeding.
